since I have to pull the drivetrain out of my 70 duster due to a fragged clutch, I figure now is the perfect time to convert to hydraulic actuation.

im planning on a pull style 3/4 diameter slave, and would like to match with a wildwood remote reservoir 3/4 master. ideally, id like to use the factory holes in the firewall.

has anyone done this, and if so, how? id really like to avoid bespoke parts and 600 price tags in any way realistically possible
 
Buddy had a McLeod hydro clutch in his 65. He never got over the firewall flex and lack of feedback the Z-bar gave him. And bleeding it was a *****....Just a observation. Hope you have better luck with it.
 
I bought a powertrain technologies hydraulic throwout bearing, it's the exact same as the American powetrain one just about 200$ cheaper. Only taken the car or once since then but its working great!
 
I think i have the pull style slave worked out.
However, a .75 master and firewall mount are giving me a headache. Solutions?

Do you have a link for that?
 
Reinforce the firewall. Make a stiff plate to bolt to the inside of the firewall. Also, it's critical to have the master cylinder lined up so when the clutch pedal is pushed, the MC pushrod moves in a straight line. Otherwise it will wear out the MC bore.

Yeah i had to call them to order it, their "mopar" street max fits an 833. It comes with the same anodized spacer that american powertrain does, 10 shims and the bleeder line. I bought a 7/8 wilwood master cylinder for 80 bucks and that worked perfect. Also since im sure it and american powertrains throwout bearing are the exact same i just downloaded the instructions from american powertrain and followed them and it was smooth sailing!

How much was the Powertrain bearing? I was thinking about ordering a Chevy or Howe bearing (for a Chevy - around $100) and putting a sleeve over the Mopar bearing retainer tube to make up for the different diameter. If I can avoid the hassle and just buy the correct Mopar diameter bearing for a reasonable price I'd rather go that route.

If you do this I hope you'll put up a good thread with photos and etc!!..........
 
Will do for sure. Actually there are two ways to skin the cat (= using a Chevy bearing):

1.) use an 18-spline bearing retainer and turn it down slightly: tube diameter is 1.417 and ID of bearing is 1.375-1.379. I'd turn it down to 1.360 to have some play.

2.) use a sleeve on the 23-spline bearing retainer (tube OD is 1.248) and (tack)weld it to the retainer.

You just need to measure the distance to the retainer face and use the appropriate shim amount or make a single thick shim.
